TYPE-W'RITING emeritus.

To all whom it may concern:

Be it known that I, GEORGE W.

invented certain new and useful Improvev ments in Type-Writing Machines, of-wliich set forth simple and efficient means for convenientlyand easily regulating the media .isni so that different color fields of a multi- Y colored rlbbonmay bebrought lnto service at will; to use selected portions of these color fields; to use selected portions ofan ordinary ribbon and to remove the ribbon entirely out of the printing'field and render its actuating mechanism inoperative so that the machine may bereadily employed for cutting stencil sheets; I 5 1 My invention consist'sfojf the'featuresof novel construction, arrangement of parts and combination of devices having for their objects the above and other ends as described and illustrated in the accompanying drawings and spec fication and set forth. in

the claims.

rice; Fig. 7 shows the spring supporting are shownand broadly claimed'in myfapplication, Serial Noa343fl25, filed November 16th, 1906. The present case relates to feae,"

tures not contained or claimed in said application, The frame of thetypewriterflreferred' to and shown inthe drawings corn prises a base 1, corner posts 2 and a top plate 0. Keyleversi are fulcruined on a rod 5 run ning from sideto side ofthe base plate 1 and are provideclwit'lifinger keys Type bars 7 are 'segmentally arranged and fu 1- crunied on a segment (not shown). which forms a part of top plate 3 and are operated to strike upwardly and rearwar'dlyagainst thefront faceef the platen 9, preferably slightly above the horizontalaxial plane thereof 1 This platen is carried by tllCEt1- riage 10 which moves from side to' side of the machine above the top plate The" letter space or step by step movements of this carriageare fc'ontrolledby a letter spacing 'mechanism (not shown in fiilllof which the vibrating dog carrier- 11 forms a part. This dog carrier 11 is fulcrunied at 12 in the supporting bracket .13 depending from the top plate 3.

The dog, carrier is actuated, at each inoveinentof the key levers 1 4' and the spaeebar 14L, advancing the car-i.

riag'e a letterspace at each key stroke. The increment of the dog carrier by the several key levers 4L isaccoinplished by means of'the universal bar 15 which extends from side to side of the machine below'the key levers lso that it is depressed by the action of any of the levers. T his motion is communicated to the dog carrier by the connecting"wires 16 which depend from the arms 17 of afuni v'ersal bar rock shaft 18 pivemiiy mounted on the base plate 1, L lhis rock shaft carries a vertically disposed arm 19 from which the pull. rod 20 extends rearwardly to the lower end of thelever 21 forming apartiof the dog carrier 11.

hon carrier which forms 'a part "of my dew spring23; It will be seen, therefore, that This lever is normally, w held in contact. ,with the stop .22 byhthe' when any key lever is depressed the pull rod 20 andthe lower end. of the lever 21 are drawn forward by the action of the universal bar let, the rock shaft 18 and the lever arms 17 and 19.

In Fig. 3, I show the general arrangement of the ribbon with relation to the machine and the novel features which comprise my invention. The ribbon 2a is shown with a dotted median line 25 which-represents the demarcation between the two color fields 26 and 27, These color fields may not vary necessarily in colcr; one may be inked with a copying ink and the other with a noncopying or record ink; also, it is understood that the ribbon may be uniformly inked throughout. The ribbon is coiled upon the ribbon spools 28 and is wound and unwound from one to the other longitudinally in either direction across the machine in such manner hat it will not obstruct the writing. To accomplish this end it is led from the right hand spool to the slotted guide arm 29,see Figs. 1, 2 and 8. The guide portion of this arm is arranged at an elevation and in an inclined plane parallel with and just below the line of sight of a written line on the platen 9. From the guide arm 29 the ribbon passes in a substantially horizontal line to the upper guide member ofthe. vibrating or oscillating and longitudinally movable ribbon carrier 31. he term vibrating or oscillating is used with reference to the motion of this member noral to the platen axis and the term longitudinal with reference to its movement parallel to such axis. This guide member 30 is shown in detail in Figs. and 6. It is preferably formed of wire attached to the upper right hand corner of the body of the ribbon carrier 31 from which it extends to the left parallel with the platen, thence forwardly and at an angle oftferty-fivo degrees in a right hand direction and in a plane parallel with the guide portion of the arm 29; thence rearwardly in a slightly higher level and in the same plane. is shown in Fig. the ribbonpasses under this rearwardly projecting part which acts as keeper, over and rearwardly under the inclined portion in a bias fold, thence over the horizontal portion and passes down parallel with theribbon support to the lower guide member 32. This guide member 32 is shown in detail in Figs. at and (3. It also consists offa suitable wire attached to the ribbon support and extending parallel therewith in an upwardly inclined right hand direction. Its upper end is bent back upon itself to act as a keeper as in the guide member 30. The ribbon passes from guide member 30 described in the manner shown in Fig. 3 to this lower guide member which it crosses in a bias fold and thence to the slotted guide arm 33, see 2, from which it passes to the left hand ribbon spool. The ribbon spools 28 are suitably supported on brackets 34: which depend from the top plate 3 shown in Fig. 1. They rotate on shafts journaled in these brackets which shafts are driven by the miter gem-s 36 which in turn are dr'ven by the corresponding miter gears 3'!" which are supported and drivenlby the main ribbon driving shaft 38 which is journaled and supported in the brackets 39 w iich depend from the top plate 3, see Fig. 1. The main ribbon spool driving shaft is revolvedv to the right at each letter space movement of the carriage 10 by means wellknown in the art through the medium of a nrain-s )rino drum and its associated letter spacing mechanism which parts are not ier shown. The main driving shaft 38 has a limited longitudnial movement by which means the driving. gears may be alterthat the generalarrangement of the ribbon spool support and driving means as shown in F 1V is duplicated on the opposite side of the machine. p

I have thus far shown how the ribbon is supported during its longitudinal movements from spool to spool during the opera tion of writing. By the arrangement of the ribbon on and between the guide members 30 and 32, I secure a vertically disposed section of the ribbon supported by the ribbon carrier 31 which is wholly within the control of said carrier, the oflice of which is to interpose this section as an operative field between the types and the paper at each printing operation in a manner hereinafter described. This vertically disposed section or portion'of theribbon, it will be observed, lies crosswise of the axis of the platen or in the same direction as the direction of the platen shift movement.

The platen shift movement in the Victor machine, to which my invention is shown applied in the drawings,; is, like most machines at present in public favor,"ina. vertical direction. This 'causing-theribbon to shift with the platen when an upper case character is to be printed. This adds complication to the ribbon mechanism to provide this additional movement of the ribbon, which" additional mechanism or increased complication is avoided by my present invention by sup- I guide member.

porting the operative or printing portion of the ribbon in a vertical or crosswise-direction of the platenthat is a direction which is the sameas, or parallel, to the direction of the platen shift. It will be seen that no additional shifting movement of the ribbon with the platen is necessary-as by supporting the ribbon in this-way it will cover the printing point'in both upper and lower case positions ofthe platen, while at the same time the ribbon is retired out of the operators line of sight in its normal position. In Fig. 3 the ribbon carrier 31 is shown as being centrally located inthe machine and having its normal operative position opposite the writing point, on the platen. The ribbon is therein shown threaded through its supporting members so as to .ex pose a section of the ribbon crosswise of the line of writing. The different color fields are thus shown as occupying different vertical sections of the ribbon their division being' represented by the dotted line 25. The

ribbon carrier31is shown ina detailed plan view 111 Fig. 6 and in side elevation in Fig.

ing edge guides for theribbon in its passage from the upper to the lower guide member.

The upper end of the right tinevis lengthenedand forms a support for'the upper It is bent at a to form an.

obtuse angle in section as shown in Fig. 4. Projecting rearwardly from its lower end are arms 40 by means of which pivotal support is effected. Its lower end comprisesa rectangular frame, the cross bar 41 of which is impinged by and forms an operating contact for the part whichactuates it. Pro

jecting from the front and just below the. bend a is a bracket "42 forming a point of attachment for the retracting spring 43. The normal position of the ribbon carrier is illustrated in Fig. 4 where'itis shown with its ribbon supporting portion inclined forwardly and fullybelow the line of vision, which is substantially at an'angle of about 45 degrees to the horizontal. It has pivotal support in the yoke 45 being mounted therein by the arms 40 on the pivot screws 44. It is preferably maintained in its proper positionby the stopplate 46 which projects forwardly from a point on the top plate 3, Fig. 4, being held against this stop by the retracting spring 43 which extendsfrom the arm 42 on the carrier to an arm 46 extending from the yoke 45. In Fig.4, the pull rod 20 is shown as carry ng an upwardly extending arm 47. At each printingoperation of the machine this pull rod, acting as a movable member of the universal bar-operated letter spacing mechanism is drawn forward, carrying the arm" 47 with it. upper end is arranged to'occupy a position two right angled bendsterminating in the Its ribbon carrier 31, especially on the cross-bar portion .41, Fig. 6. I Forward movement, of

this arm as a partofthepull rod20causes the ribbon carrier 31 to oscillateon its -pi v otal support and carry the ribbon toward port-s by means of whichlit 'is-Icaus'ed to cover and uncover-the wr ting point at each Writ ,ing operation andthe: arrangement of the ribbon on the vibrating" ribbon carrier which. creates'an operative field ofthatseo tionbf the'ribbon'whichgis led at'this point longitudinally-ina direction crosswise of of normal contact with the "lowerjend of the the platen and to properlyinterpose theverv the platen. To selectively employdifferent] color fields 'of this operative section,;o r. different portions of the respective colorfields, I

I provide means for; moving the ribbon cars rier and itsguide 'members'in aj direction parallel with theplatent) to indexed pre Q p, a

determinedpositions in relation to the impression point ofthe types'Bon the platen 9. The yoke 45 in which the ribboncarrier 31 is pivotally'inounted is rigidly attached to therod 48,Fig. 5. This rod has its main] v I support in the arms'51 shown on eitherside of theribbon carrier. These arms are sup-f por'tedat the rear by the cross-bar 50 which in turn is secured toa lug 49 forming a part of the top "plat s, see Fig. 4, and at their forward ends by the screen plate 52, also having its support on a: partofthe top plate 3 which'has. been cut' away for the purpose of making this illustration. The

ribbon carrier 31-projects through a slot 52*" in said screen 'plate,"asshown in Fig. 3; The

rod 48 supports the yoke 45 intermediate of the arms 51 and passes through and extends beyondthem on either side. The longer "or right hand projection is extended and "forms parallelportion 48 which passes through and is supported by'a' part of the top plate This off-set portion 48 in its support in thetop. plate 3 serves to secure the rod 48 against revolution, whilepermitting its axial movement. Means for 1" giving this "rod 48 indexed axial movement may be seen by an I I inspection of'Figs. 1, 2 and 3,111 which the operating rock shaft 53 is. shown in detail supported at its forward end in the corner which depends from the right ribbon spool 126 post 2 and at its rear end by the bracket 54 I shaft support 134. This rock shaft 53 has the corner post 2 and is'bent at' a point 'i' earv the post to extend upward as an operat- The lever armengages at its slotted 1 ing lever 56 which terminates in the ring or finger grip 57. In Fig. 2, in which a portion of the front right hand corner of the top plate 3 is broken away, is shown a plan view of means for indexing this operating lever 56 in its various angular positions. Fig. 3 shows the same in front elevation and Fig. 4: in right elevation. Mounted on the post 2 is supporing plate 58 shown in plan in Fig. 7. It is attached thereto by the hollow bolt 59' and nut 60. This hollow bolt serves as a bearing for the rock shaft 53. The screw 61 lrceps the plate in a vertical position onthe bolt. The upper end of the plate which is made from spring sheet metal is flexedforwardly away fromthe post 2. This plate has the forwardly projecting perforated ears 62. Revolubly mounted across the front of the plate and between these ears is the indexing arbor 63. This arbor is hexagonal insection and has on alternate facets the transverse notches 64 which are locatedin various positions longitudinally of the arbor and are alined in their various positions parallel to the radii of the operating lever 56 in its various angularly indexed positions. The arbor is revoluably adjusted by the thumb wheel 65 whichis paned to correspond with the arbor and bears on its panes indicating characters 66. The arbor is held in its various adjusted positions by the spring pressure of its supporting plate 58 directed toward the operating lever 56 which. is comparatively rigid and is held against the pressure of this spring member by the hub 55 of the lever arm 55 which operates as a stop collar against. the bracket 5i, see Fig. 1, to oppose endwise movement of the rock shaft 53 in the direction of the lever 56. The sector portion of the plate 58, 67 is divided into indicating color fields; thus, the portion 68 may be black and the remaining portion 69 red. I i

' The operation of my device is as follows: If a two color ribbon be used, it is wound upon the spools as usual, carried across the machine from side to side and threaded through the supporting members on the centrally disposed *ibratiug carrier, in such manner that its color divisions in the vertical operative field are reversed in their order from right to left to'the color index for the operating lever. The notches on one face of the indexing arbor are arranged to lie wholly opposite one color on the index plate, those on another face opposite the remaining color field while the notches of another face embrace both, fieldsand also a notch which indicates a blank. The opera tor selects the colorfield desired by revolving the arbor by means of the thumb wheel to expose the proper indicating character on that wheel. This brings those notches into lav which are ooaositc the are er color V ll 1 P field on the index. The operator then brings-the operating lever into engagement with anotch in that field. The operating arm transmits movement parallel to the tervals, and the relative effective leverage of the operating lever and the connecting lever arm are arranged to move the ribbon carrier sidewise, longitudinally of the platen and transverse of the vertical operative ribbon field a distance approximately that of a type .face so that each change of the operating arm interposes' a fresh longitudinal portion of the ribbon for use. If an ordinary ribbon of one color is used then the indexing arbor isturned to bring a. face bearing notches covering the entire widthwise dimension of the ribbon. By bringing the operating arm into engagement with these various notches the entire width of the ribbon maybe used in success ve longitudinal field's. During the operations thus described the operating portion of the ribbon carrier'al has remained in operative contact with the driving arm 86. When it is desired to prepare stencils for mimeograph work or to cause the types to strike directly against the stencil sheet or paper without the ribbon. being interposed between them, the operating arm is engaged in a notch to the right on the indexing arbor indicat-ed as blank. 'This moves the ribbon carrier in a corresponding direction to such an extent that it is entirely to the right of the writing point and the operating portion l-l'is out of contact with the driving arm 47 and is not thereforeribrated during the operation of the machine. During this time, the ribbon carrier is held by the stop at; in position for reengagement with the driving arm 47 when the operating arm is again shifted.

While I have described the mechanism as operating in a certain order or sequence it is to be understood that the several parts of the device may be differently arranged or manipulated in any desired order without departingfroin my invention. The construction herein set, forth is preferential only as applied to a particular machine and is susceptibleof change in detail for application to any machinewithout departing from the invention in which Iclainri 1.
